Hi Devin

With respect to installing the new saa7164 driver (from kernellabs.com/stoth/saa7164-stable.git) into my ubuntu/mythbuntu 10.10 system (x86 32bit kernel 2.6.35-30), assuming that I've already put the correct firmware in place, do I just replace my existing 
saa7164.ko with the new one created by the above make and reboot ? Or is there more to it ?

Thanks,
Declan
